[Summary] In the treatment of very-early stage hepatocellular carcinoma ( HCC) , several therapies have their own strengths . Liver transplantation, surgical resection, and percutaneous ablation are the most effective procedures for very-early stage HCC.Liver transplantation is difficult to carry out due to lack of donors .Surgical resection and percutaneous ablation are the most commonly used methods with ideal effects .Compared with surgical resection , percutaneous ablation has its obvious advantages in patients with small HCC and senile patients , but the recurrence rate is relatively high .When the above mentioned three methods are not feasible , transarterial chemoembolization is a remedial treatment .Combined use of local therapy is superior to topical therapy alone and suitable for patients with unresectable lesions .Theobserving therapystill needs more clinical studies to confirm its safety and effectiveness .

A remarkabale inhibitory activity was exhibited by the aqueous extract from Rhizoma smilacisglabrae(RSG) against both picryl chloride(PC)- induced contact dermatitis and sheep red bloodcells (SRBC)- induced footpad reaction.The effect of RSG was displayed more distinctlywheng given after than before the 2nd antigen challenge.RSG also showed a marked anti-in-flammatory activity against xylene- induced ear and egg whiteinduced footpad edema.Addi-tionally,RSG did not show a potable influence on IgM- and IgG-PFC counts against SRBC inmice.An increase but not decrease in serum hemolysin level,however,was observed in both groupsof RSG,peralleled with the finding that hemolytic plaques in PFC test were obviously biggerthan those in control.These results suggest that RSG has a selective activity to suppress the cellularimmune response without inhibiting the humoral immune response.The suppression to cellular im-munity by RSG may be presented mainly through affecting the inflammatory process after lym-phokine release.

Objective To observe the effects of extracorporeal shock wave therapy (ESWT) on spasticity of biceps brachii after stroke. Methods 12 patients with spasticity of biceps brachii after stroke were divided into control group (n=6) and ESWT group (n=6). The ESWT group received a session of ESWT and the control group received placebo treatment. All patients were assessed before and immediately after treatment, including integrated electromyogram (iEMG) and co-contraction ratio during maximum isometric voluntary contraction (MIVC) of elbow extension with surface electromyography, the modified Ashworth Scale (MAS) and content of shoulder and elbow of Fugl-Meyer Assessment (FMA). Results The scores of MAS and FMA, the iEMG and the cocontraction ratio of biceps brachii improved in the ESWT group after the treatment (P<0.05), and improved more than those in the control group (P<0.05). Conclusion ESWT can immediately relieve the spasticity of biceps brachii, inhibit the cocontraction of biceps brachii during elbow extension and improve the motor function of upper limb in patients post stroke.

To compare the curative effects of two surgical treatment methods for open angle glaucoma and cataract patients.
●METHODS: Totally 69 patients with primary open angle glaucoma and cataract were divided into two groups:group A and group B. Thirty- four patients (34 eyes) in group A underwent small incision non -phacoemulsification cataract surgery combined with trabeculectomy, just combined operations, 35 patients (35 eyes) in group B underwent small incision non -phacoemulsification cataract surgery beyond 6mo after trabeculectomy, just two stage operations. Postoperative intraocular pressure at 1wk and 3mo, postoperative corrected visual acuity and filtering bleb at 3mo were observed, and intraoperative and postoperative complications were compared. All the patients were followed up for 3-6mo.
● RESULTS: All the visual acuity were increased compared with that before surgery in two groups, the difference was not statistically significant. All the intraocular pressure was controlled in two groups, the difference was not statistically significant, and the difference about the filtering bleb was neither statistically significant ( P > 0. 05 ). There were no serious intraoperative and postoperative complications in two groups.
● CONCLUSlON: The two stage operations and the combined operations both can control theintraocular pressure and improved visual acuity of open angle glaucoma and cataract. The two stage operations may prevent a second operation for post trabeculectomy cataract, allowing earlier visual rehabilitation.

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.

Objective To investigate the expression of endothelin-1 (ET-1 ), nitrogen monoxidium (NO), vascular endothelial growth factor (VEGF) and brain tissue VEGF induced by chronic intermittent hypoxia (CIH) in aged rats. Methods The CIH model of aged rat was established by using intermittent hypoxia. The levels of ET-1, NO and VEGF in the plasma were detected at 3, 6 and 9 weeks after experiment in each group. The expression of VEGF in brain tissues and the pathological changes of the vessels of the cerebra and the ratio between the thickness of vessel wall and external diameter (WT%) were observed. Results In CIH group, the ET-1 and VEGF levels increased, however NO level decreased. The levels of ET-1 and VEGF were higher at 3 weeks in CIH group than in UC group (t=2.47 and 2.38, both P<0.05), however NO level was lower in CIH group than in UC group (t=2.39, P<0.05). VEGF levels increased significantly at 9 weeks in CIH as compared with UC group [(171.1±13.5) pg/ml vs. (109.8±8.6) pg/ml, t = 3.46, P< 0.01]. The levels of VEGF in CIH group increased remarkably at 9 weeks as compared with 3 weeks [(129.3±12.3) pg/ml, t=2.38, P<0.053. VEGF levels in CIH group showed positive correlation with the time of intermittent hypoxia. The changes of cerebral vessels in UC group were not found, while the aged rats in CIH group showed cerebral neuron cells swelling and blood vessel hyperplasia. The WT% of cerebral small artery was more apparent in CIH group than in UC group at 3 weeks (t=2.34,P<0.05). The expression of VEGF in cerebra was higher in CIH group than in UC group in the three stages (r=2.37, P<0.05). There was an aggravated tendency in the change of the expression of brain tissue VEGF and WT% over time. The change was more apparent at 9 weeks than at 3 weeks (t=2.32 and 2.35, both P<0.05). Conclusions CIH can induce an increase in the expression of ET-1 and VEGF, a decrease in the expression of NO in aged rats. The over expression of VEGF and the disbalance of ET-1 and NO levels can cause brain cellular swelling, arteriola vessel wall thickening,lumens stenosis.
